The synthesis process of phenyl silicone oil has entered a new era of green and intelligent technology, with a generational leap in technology accelerating the process of domestic production


1.The fourth-generation process iteration upgrade and intelligent aggregation achieve precise control
In recent years, the domestic synthesis process of phenyl silicone oil has completed four key iterations, fully moving from the traditional extensive mode of acid-catalyzed polycondensation to a green and intelligent system that integrates microchannel reactors, ionic liquid catalysis and AI parameter optimization. The latest industry data shows that the fourth-generation synthesis process has shortened the polymerization reaction time from several hours to within 10 minutes, stabilized the molecular weight distribution index within the range of 1.1 to 1.3, achieved a phenyl positioning accuracy of ±0.3%, and the one-time synthesis success rate of high-end products exceeds 95%, significantly enhancing the batch consistency and performance stability of the products.

2. Green manufacturing has achieved remarkable results, with a significant reduction in energy consumption and emissions
Green transformation has become the core main line of industry development. The new generation of processes, through the integration of solvent-free production, closed-loop monomer recycling and other technologies, have achieved a 42% reduction in energy consumption per unit product, a 38% reduction in CO₂ emissions, and a closed-loop monomer regeneration rate exceeding 90%. Meanwhile, the use of solid superacids and other environmentally friendly catalysts to replace traditional liquid acids and bases has completely solved the problems of wastewater discharge and catalyst residue. The relevant demonstration production lines have passed the green manufacturing system certification, laying a foundation for responding to green trade barriers such as the EU's CBAM.

3. Core bottlenecks have been continuously broken through, and the self-sufficiency rate of high-end products has increased
In response to the long-standing bottlenecks in the industry such as the reliance on imported core catalysts and the difficulty in removing trace metal residues, research institutions and the industrial sector have worked together to make progress in the domestic substitution of platinum-based catalysts and precise post-treatment technologies. At present, the mass production technology of ultra-high purity (≥99.99%) phenyl silicone oil is gradually maturing. By 2025, the import dependence of high-end products has dropped from 48% in 2020 to 31%. Among them, the radiation-resistant grade products can withstand a gamma ray dose of 2×10^8 rad, meeting the protection requirements of key equipment in the nuclear industry.

4. Process upgrading drives transformation, and customized services have become a new trend
Technological innovation drives the industry to transform from general-purpose products to customized services. By precisely regulating the phenyl content and molecular structure, it is possible to achieve personalized performance indicators such as controllable refractive index within the range of 1.43 to 1.55 and low yellowing (ΔYI<3), meeting the demands of high-end scenarios like LED packaging and semiconductor manufacturing. Industry analysis indicates that in the next five years, cutting-edge directions such as atomic economic synthesis and bio-based silicon source substitution will become the focus of research and development, driving the position of phenyl silicone oil in the global high-end silicone value chain to make a leap from "following" to "keeping pace".
